l To all whom it may concern:

Be it known that CLYDE DAVIS and CHARLES E. HARDING, citizens of the United States, residing at Sioux Fallsin the county of Minnehaha and State of outh Dakota, have invented certain new and useful Improvements in Bed-Trays and Dressing- Tables, of which the following is a specification.v

This inventionis an'attachment for a bed and is more particularly adapted for the use oflinvalids either at home or in the hospital and may be used for serving meals or durin as a support for instruments and dressing surgical operations so that articles place, thereon will be conveniently acces- "sible for use as required, and when not desired for use it may be readily carried beneath the bed in such a position as Wlll permit it to be immediately swung to the oper- "ative position with little effort.

In most of the devices in commonuse, the arrangement of parts is such that when not in use, the device is still in evidence and lusually more or less in the way. It seems "customary in providing attachments to make them in such a manner that when the need has passed, they must be either removed bodily fromthe bed or else swung to one side where they may still be seen.

The utility of such devices is great and they are especially. valuable when it is desiredto serve meals to a patient or it becomes necessary to give attention topersonal hygiene, or to hold articles usually employed in surgical cases, either during the operation'or in changing the dressings thereafter. One object of this invention is to provide an adjustable tray and table that may be quickly and easily placed in an operative position for use and which may be as quickly and easily placed in an inoperative position and out of the Way in a more or concealed position ready for immediate use should it be required.

Another object of this invention is to provide atray'and surgical dressing table and instrument. table adapted for bed use that may be attached to the bedat different places without disturbing the bed clothing and at the same time leave sufiicient space between it and the patient.

A further object of this invention is to provide a slidable table and tray mounted in suitable guides and carried by rotatable supports connected to a rail of a bed and retained in a plurality ofpositions both operative and inoperative.

A still further objectof this invention is to provide a bed with an adjustable table and tray, that when in use may be supported for use over the bed and patient or occupant, and

ports, a supporting member adapted to slide in the ides, a brace and stiifening member secure tothe under surface of the supporting member, an engaging element mounted adjacent one end of sald supporting member, stops on said member for limiting its movement relative to the guides, means on the supports. for preventing rotation of the guides, a bar extending between the clamps to hold them in a spaced relation, anda curved arm rotatably mounted on said bar and having its free end adapted to engage with the brace or stiffening piece mounted upon the under side of the supporting member when in one position, said arm servin as a stop means when thesupporting mem er is placed in an inoperative position, means for maintaining the arm in a plurality of positions with respect to said'bar, said supports being rotatably mounted in the clamps are thus adapted to swing in vertical planes so that the supporting member may be placed beneath the bed at which time the arm may be engaged with one end of said member to prevent movement in the guide, and means for retaining the clamps in a plurality of positions with respect to the rail.

One practical form of construction and assembly will be described and illustrated in the accompanying drawings, in which Figure 1 is a side elevation of a bed with the tray and table secured thereto so that the support member is in an operative position, the dotted lines showing other positions relative to the rail of the bed,

,Fig. 2 is a partial vertical sectional View of a bed showing the table and tray in the same position as illustrated in Fig. 1,

Fig. 3, is a top plan detail of one of the guide members with a portion of the supporting member with one of the stops thereof in engagement with the guide member, and

Fig. 4 is a sectional view through the boss or hub of the arm carried on the bar between the clamps.

In the preferred embodiment about to be described a bed having a head board 5 and a foot board 6 is provided.- The head and foot boards may be joined in the usual way by means of the rails, one of which is shown at 7. This rail 7 is of the usual L- shape in cross section such as is customarily employed with beds of the brass or iron type. The rail 7 may be connected with the foot and head boards in any usual or customary manner.

In order to clamp the device securely to the rail 7 two clamps are employed that are formed of the sections 8 and 9. These sections are approximately L-shape and when clamped together provide a recess that is shaped to conform to the cross section of the rail 7. The two sections 8 and 9 may be held together by any usual means such as the bolts 10. The section 8 is preferably provided with a bearing indicated at 11. As each of the clamps are similarly formed the bearings 11 will have their holes in alinement.

Extending between the sections 8 of the clamps there is a bar 12 that may be rigidly secured in the bosses 13. If desired this bar 12 may be provided centrally with the splines 14 and 15. These splines or ribs are preferably spaced diametrically as shown in section in Fig. 4. These ribs or splines 14 and 15 are adapted to cooperate with a boss or hub 16 that has suitable key ways out therein, said boss or hub being mounted upon the bar 12. From the boss or hub 16 there springs an arm 17 that is provided at its free end with a projection 18 to serve as an engaging member. p

In each of the bearings 11 there is rot-atably mounted a support 19 that is approximately U-shaped. The lower or vertical limb is rotatably mounted in the bearing 11. The upper end has rotatably mounted thereon a suitable guide member 20 that is provided with a slot 21. As shown the guide member 20 is approximately L-shaped and is provided with a rounded end 22 having a bearing therein to cooperate with the other vertical limb of the support 19.

As shown the slot 21 projects horizontally in a manner to cooperate with the guide member 28 carried by the other support. These guide members and their slots serve to slidably mount a table or tray 24 which acts as a supporting member. In order to provide stiffness for this supporting mem ber 24 a brace 25 is secured to the under surface thereof. As shown this brace 25 is preferably T-shaped in cross section and the vertical limb tapers and has its greatest height at the retained end of the supporting member.

The vertical portion which may be indicated at 26 is adapted to engage with the projection 18 carried at the end of the arm 17. If desired suitable notches or other usual means may be employed.

The supporting member 24 is provided at the opposite end with a U-shaped engaging member 27. This member 27 is adapted to engage with the projection 18 when the supporting member 24 is moved to the left as shown by the dotted lines in Fig. 2. This will serve to hold the member 24 against sliding movement or accidental return to the fulliline position. This will provide for extending and retaining the article supporting member 24 over the adjoining bed. One edge of the supporting member 24 may be provided with the spaced stops 28' and 29. These stops are adapted to engage with the sides of the guide member 20 one being shown in engagement in Fig. 2. These stops serve to limit the movement of the supporting member 24 in its sliding relative to the guides 20.

The guide members 20 may be provided with a suitable locking arrangement generally indicated at 80. This lock may be of any usual type of construction that will serve to maintain the guides immovable with' respect to the supports 19. This is done to prevent rotation of the 7 guide member when it is desired to hold the supporting member 24 in its operative position as when extended over the bed.

In Fig. 2, as shown bv the dotted lines, the supporting member 24 may be slid to the left through the guides 20 and 23 until the stop 28 engages with the guide 20. The projection 18 carried by the arm 17 may then be disengaged from the engaging member 27 The locking device 30 is then released whereupon the supports 19 may be rotated in their bearings 11 and their other ends rotating in the bearings 22 of the guide members so that the supporting member 24 will be maintained in a horizontal position during such movement.

The continuing of this movement will place the supports 19 so that the guide members 20 and 23 are below the rail 7 as shown by the dotted lines in Figs. 1 and 2. The projection 18 being disengaged from the member 27 the arm 17 may then be swung so that the projection 18 will engage with one end of the support 24, as shown by the dotted lines. For this purpose .the projection 18 extends from arm 17 in such a manner that an angle or shoulder is formed therebetween that will cooperate with the end of the member 24-.

In order to provide for movement of the "am 17 a is adapted to slide on the bar 12 until it disengages with the splines or ribs 14 and 15 whereupon it may be rotated so as to extend downward in the opposite direction as shown in the dotted lines in Fig. 2. When the arm is moved back to engage with the splines'or ribs 14 and 15 it will be firmly held against rotation and this will prevent any movement of the member 24:.

.As shown inthe several figures the table or tray is adapted to be positioned over the bed and'above the patient so as to provide clearance therebetween. Fig. 2 may be considered the operative position. The supporting member 24 will then be rigidly held against undue movement and the brace 25 extending longitudinally thereof tends to stiflen it. The arm 17 by engaging with the vertical portion 26 of the brace will further serve-to support the member 24:. As this "arm 17 is curved it does not interfere with thebed clothing in any way.

The dotted lines in Fig. 2 show how the supporting member 2 1 may be positioned beneath the bed in the inoperative position. This placing of the table or tray will permit 1 its being immediately available for use. The

supporting member 24 may carry, from the operative to the inoperative position such articles as itmay be desired to have convenient for future dressings if employed with a surgical case.

Whatwe claim is: 1. A tray and dressing table, which comprises spaced sup-ports rotatably connected withthe railof a bed, a slidable article supporting member mounted in guides carried by the, supports, means for limiting the travel of the supporting member, means for retaining said member in a plurality of positions, and a rotatable brace extending be- "neath the supporting member and operatively connected with the spaced supports,

said member being supported horizontally ing rotation of the guide elements, and a rotatable. arm serving as a support and lock for the slidable supporting member 006peratively connected with the clamps, the rotatable mounting of the supports permitting the supporting member to be positioned over copies of this patent may be obtained for swinging in parallel vertical planes,

the bed and beneath the bed in a horizontal plane.

3. A bed tray and surgical dressing table, which comprises spaced supports connected with a rail of a bed and adapted to rotate in parallel vertical planes, a supporting member slidably connected with the sup ports, a longitudinally extending brace operatively connected with the supports, and means locking the supports and supporting member in a plurality of positions, said supporting member being maintained horizontal in each position.

4. A bed tray and surgical dressing table, which comprises spaced clamps adapted to be removably secured to the rail of a bed, a bar extended therebetween, a support rotatably mounted in each clamp and capable of swinging in parallel vertical planes, guides rotatably mounted adjacent the upper ends of the supports for movement in vertical planes independently of the movement of the supports, an arm rotatably mounted on the bar and provided with an engaging end, a supporting member slidably mounted in the guides adapted for cotiperation with the engaglng end of the arm when in a plurality of positions, spaced stops on the supporting member for limiting the travel of said member, means carried by the guides for preventing their rotation on the support, said supports upon rotation being adapted to position the supporting member in a spaced relation to the upper surface of the bed in an operative position or spaced beneath it in an inoperative position.

5. A bed tray and surgical dressing table com-prising spaced clamps adapted to be removably secured to the rail of a bed, a bar extended therebetween, a support rotatably mounted in each clamp and capable of guides rotatably mounted adjacent the upper ends of the supports for movement in vertical planes independently of the movement of the supports, a supporting member slidably mounted in the guides, and an arm rotatably mounted on the bar and provided on the end with a right angle extension, said right angle extension adapted to engage the under side of the supporting member when in one position and the end of the supporting member when in another position.

In testimony whereof we affix our signatures in presence of two witnesses.
